WN has launched one of its best sales in years, applicable for several off peak weeks in winter (and excluding Friday and Sunday travel). The fares that are most likely to be of interest to this forum are the short haul $49 ow fares -- seemingly limited to about 500 mile trips. In years past, competitors have matched these fares, and often times you've been allowed to fly to hubs outside the 500-mile perimeter and then "double back." This is obviously useful to both earn extra miles or take advantage of hidden city ticketing.
The sale runs until Thursday. I'd start looking for matches this afternoon.

Given how high domestic fares have climbed, some readers are also likely to be interested in the longer haul fares, at least if your schedule works for those dates.
